  [AMDGPU] SILoadStoreOptimizer: tweak API of CombineInfo::setMI. NFC.

Change CombineInfo::setMI to take a reference to the
SILoadStoreOptimizer instance, for easy access to common fields like
TII and STM.

  -----------
  [AMDGPU] SILoadStoreOptimizer: use separate lists for AGPR instructions

Using separate lists for AGPR and non-AGPR instructions seems like a
cleaner solution than putting them all in the same list and then later
refusing to merge instructions of different AGPR-ness.

  Log Message:
  -----------
  [AMDGPU] SILoadStoreOptimizer: reject AGPR DS_WRITE sooner

Rejecting AGPR DS_WRITE instructions before adding them to any mergeable
list seems cleaner than adding them to the list and rejecting them
later.
